Emergency Alert

NOTE: This is a Software Selling Feature.

This feature allows the radio to send emergency alerts to other radios within its Direct Mode Operation

(DMO) coverage by pressing the Emergency button.

Even in Trunked Mode Operation (TMO), the radio monitors a special DMO emergency frequency for

possible emergency alerts and responds to them by automatically joining the emergency call.

To initiate the emergency alert, the radio must be in MS-MS DMO mode or out of coverage in TMO

mode. The alert is not sent to the dispatch console.

To receive the emergency alert, the radio must be in DMO or TMO, within RF range of the initiating

radio, and must not be in a call. When the radio receives the emergency alert, it joins the call

automatically.

The following table illustrates the dependencies between the current radio mode and the type of

emergency operation:
